Security Information and Event Management

SIEM refers to specialised software that collects security logs from devices on a network, then analyses and reports on them in order to help identify possible threats and security incidents.

SIEM systems combine security event management and security information management, providing continuous automated analysis for cyber security threats. These systems improve the efficiency of cyber security, freeing up resources while ensuring businesses maintain a strong security posture.

SIEM services help businesses maintain GDPR compliance

Protection of personal data must be a priority for every business.

The Information Commissioner’s Office (ICO) is expecting businesses to invest in the latest cyber security technology, including SIEM. Businesses, the legal, financial and medical industries in particular, are facing fines for incorrectly storing and protecting data.

Whether you are an enterprise-level business or an SME, you need to ensure that you have the correct cyber security measures in place. SIEM helps your business maintain GDPR compliance and provides powerful tools for keeping data safe in an online world.

Proactive monitoring of your systems improves efficiency while maintaining security

With businesses increasingly dependent on technology for operation, it can be difficult for internal teams to constantly monitor and effectively respond to threats.

SIEM tools streamline this process, collecting and processing data from across your network. This proactive approach gives you the peace of mind that your systems are being constantly monitored for any signs of malicious activity. Any security events are flagged for teams to investigate and take action if necessary.

Identify trends and correlate usage patterns throughout your network

One of the most powerful benefits of SIEM software is its ability to identify relationships between network activities and alert you to any anomalies.

SIEM is capable of catching suspicious activity early. For instance, this software tracks login attempts and will send an alert when a predetermined number of failed logins are attempted. These alerts catch such activity and give you time to take action before they become a problem.

The customisable nature of SIEM software means you can adjust the rules based on your own experiences and best practices to provide powerful protection for your network.

Endpoint protection

End-user devices are often the entry point for malicious actors mounting an attack on an IT network.

Ensuring robust protection for laptops, desktops and other devices connected to your network provides the first line of defence against data breaches. This is especially important with more businesses adopting hybrid work environments; devices connecting from off-site locations need to be monitored as well.

SIEM software integrates with endpoint protection systems to detect threats in both remote and on-site devices to give your business an added layer of security.

IT Support with Client

Instant response for issues allows you to quickly deal with any threats

A quick response is critical for mitigating the damage of a cyber attack.

SIEM software offers instant alerts for any security events, meaning teams can respond quickly and effectively to any potential threat. By identifying which area of the network has been compromised,  you can limit the damage done by an attack and quickly get your systems back up and running.

What are the benefits of using SIEM software?

SIEM software aggregates all event log data from different systems in one centralised location. Automating data collection in this way carries several benefits:

Frees up resources: Allowing SIEM systems to collect and analyse data means security teams can spend less time gathering information manually and more time responding to threats.

Provides a historical view: Security teams can review SIEM data to identify trends and potential threats over time.

Helps with compliance: Businesses need to comply with regulations such as GDPR. SIEM software helps with this by providing a detailed audit trail of all activities.

Enables rapid response to threats: By proactively monitoring all systems all the time, threats can be quickly flagged and identified by security teams. This level of visibility means breach attempts can be either stopped or their damage limited, meaning businesses can be assured of the integrity of their data.

Bolts onto other prevention methods:  SIEM software can integrate with other cyber security measures as an additional layer of defence, ensuring businesses maintain a strong security posture.

What type of data can be collected and monitored with SIEM services?

A SIEM service can collect and monitor a wide range of data, including but not limited to:

  • System logs
  • Security logs
  • Network traffic logs
  • Application logs
  • Database logs
  • Email server logs

By collecting and monitoring this data, businesses can enjoy increased visibility into their network security posture and be alerted to any malicious or unauthorised activity.

What are some of the best practices for using a SIEM service?

SIEM collects and analyses data from across IT networks, which can result in huge amounts of data being processed. For this reason, SIEM software is built with customisable rules that allow businesses to fine-tune the settings to their specific needs.

Check for false positives: It’s important to verify that events being flagged and triggering alerts are not false positives. There are many different types of suspicious activity, and if the wrong events are selected then security teams will be overwhelmed by alert notifications without any insight into where to focus their efforts

Configure alerts: The next step is to configure alerts so that only important events are flagged and sent as notifications. Too many false positives can quickly become overwhelming, so it’s important to be selective with what events trigger an alert.

Create reports: Once alerts are being sent, it’s important to create reports that provide more information on the events that have been flagged. This will help security teams to investigate and determine whether any action is required.

How can I ensure the safety of my data if I use SIEM services?

A SIEM service can help to protect data by providing increased visibility into the security posture of a network and identifying malicious or unauthorised activity. By monitoring all event data in one location, businesses can be alerted to any threats that may pose a risk to their data. In addition, many SIEM services offer features such as data loss prevention (DLP) and malware detection, which can help to further protect data from being compromised.

What is the difference between SIEM software and a log management service?

A SIEM service is specifically designed for security event monitoring, while a log management service deals with all types of event logs (security, system, network, etc.). A SIEM service will typically have more features than a log management service, such as the ability to analyse data and generate reports.
